Tim's House serves as the central hub from which you access all the different worlds of Braid. Each door in the house leads to a distinct world, each with its own unique time-manipulation mechanic. Initially, only a few doors will be open, and you'll unlock more as you progress through the game and collect puzzle pieces. The house itself also contains some subtle narrative elements and hints about Tim's past and motivations.
- World Doors: Each door represents a different world (World 2, World 3, etc.). Entering a door takes you to the first level of that world.
- Bookshelves: Interact with the books on the shelves to read snippets of Tim's thoughts and the game's lore. These provide crucial context for the story.
- Paintings: As you collect puzzle pieces and complete worlds, paintings will appear or change in Tim's house, visually representing your progress and the unfolding narrative.
Don't rush through the hub world. Take your time to read the books and observe the changes. They are integral to understanding the deeper themes of Braid and can offer insights into the puzzles you'll encounter. The order in which you tackle the worlds is somewhat flexible, but generally, the game guides you through them in a specific sequence to introduce mechanics gradually.
